BIOS archive for the Samsung NP300E4C, regional model AD2BR, provided as a 2.87 MB RAR. The name gives no board number, project name or revision, so compatibility must be confirmed from the model sticker and PCB markings. Such a dump is used to rewrite the SPI flash chip when the laptop is bricked by a failed update or shows no display. Read and keep the original contents with a hardware programmer before writing, and make sure the image size equals the capacity of the chip installed on the board.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
